' DISCHARGEDOOR-OPERATING MECHANISM.

Application filed December 24, 1915.

To all whom it may concern Be it known that I. GEORGE W. RISTINE, J12, acitizen of the United States, residing at No. 1716 East Fifty-fifthstreet, Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Discharge-Door-OperatingMechanism. of which the following is a specification.

This invention relates to railway dump cars, including that type knownas a general service car, some types of which are illustrated anddescribed in United States Letters Patent No. 791.348, granted to C. A.Lindstrom and John F. Streib, in which the bottom is partly orsubstantially conmosed of a plurality of discharge doors which arehinged along one edge, and which at their free edges are supported bythe operating shafts which have heretofore been supported in stationarybearing members secured to the transverse members of the under-frame.and an object of the invention is to provide means for supporting theoperating shafts independently of the trans verse members of theunderframe, which means will take the place of or be auxiliary to theordinary bearing members secured to the transverse members of theunderframe.

Another object of the invention is to pro vide movable means forsupporting a bodily movable discharge door operating shaft from the sidewall of a car.

A further object of the inventionis to provide a discharge dooroperating mechanism, for railway dump cars, having a movable memberadapted to be moved by the door operating shaft into or out ofsupporting position relative to said shaft.

With the above and other objects in view, the invention resides in theconstruction, arrangements and combinations of parts hereinafterdescribed and claimed.

Referring now to the drawings in which like reference characters referto like parts. Figure 1 is a plan view of a car embodying the invention,Fig. 2 is a side elevational view of the same, a portion of one of theside stakes being broken away to more clearly show a portion of the dooroperating mechanism; Fig. 3 is an enlarged cross sectional view taken onthe line 3-3 of Fig. 1: F 4 is an enlarged detail side elevational viewof a portion of the car. the side stake being om t d to m e y u tratethe levee- Specification of Letters Patent.

tion; Fig. 5 is a sectional view taken on the line 55 of Fig. 4, theside stake being shown, and Fig. 6 is a sectional view taken on the line66 of Fig. 4, portions of the side walls being removed to more clearlyillustrate the invention. The description being confined. to thatportion of the car which is illustrated, it will be understood that theopposite end of the car is in all respects similar to that which isshown.

Referring now in detail to the drawings, 1 indicates the center sill, 2the end sill, 3 the bolster. and 4 and 5 the intermediate tra ns\-*ersemembers of the underframe, all of which may be of any desiredconstruction and suitably connected.

6 indicates the car body which comprises end walls 7 and side walls 8.all of which are suitably connected. The side walls 8 are eachpreferably provided with a vertical upper portion 9. a downwardly andinwardly sloping intermediate portion 10, and a hori- Zontal lowerportion 11, such horizontal portion preferably resting on and beingsecured to the end portions of the transverse members of the underframe.To stiffen the body of the car the side walls, at intervals throughouttheir length, are provided with stakes 12.

The lower edge portions of the side walls, as indicated at 13, and theupper edge por tions of the center sill and transverse members of theunderframe define discharge openings in the car bottom, which openingsare closed by doors 14 and 15. which are preferably hinged along theiredge portions to bracket members suitably connected with the center sill1.

To operate the discharge doors 14 and 15 and for the purpose ofsupporting such doors in their closed positions, shafts 16 are provided.In the embodiment of the invention as shown in the drawings. each ofthese shafts is rotatably and slidably mounted in slots formed in themembers 17 which are preferably secured to the bolster and transversemembers, and are also mounted in a -movable member 18 which ishereinafter To each of these,

more fully described. shafts is preferably secured a plurality ofspirally grooved drums 19, to each of which a chain 20 is connected, theother end of the chain being connected to the free edge of one of thedoors. preferably through the medium of a member 21 which is connectedwith a serrated shoe portion 22 which isadapted to engage with aserrated roller 23 ltl secured on the operating shaft, which roller maybe integral with the spirally grooved drum 19.

Intermediate the transverse members 4 and 5 of the underframe a bracketmember 24 is provided having a top portion which is preferably securedto the horizontal portion 11 of the side wall and having a side portionsecured to one of the side stakes 12. This member is preferably providedwith spaced vertical ribs 25 which are preferably integral with the topand side portions and are provided with notches 26 open at one endadapted to receive the shaft 16. These ribs 25 support the shaft 16directly when such shaft is in the notches 26. Between the ribs 25,rollers 27 and 28 are mounted on pins 29 and 30, which pins are heldagainst longitudinal .movement by cotters or other suitable means. Themember 18 is movably mounted on the roller 28, and at its end portion 31is preferably provided with a notch 32 in which the shaft 16 isrotatably mounted. It will be understood that if desired the notch 32may be modified and the end portion of the member 18 formed in any othersuitable manner to provide a bearing for the operating shaft. When theoperating shaft is in the position as shown in the left hand portion ofFig. 3, and Figs. 4, 5 and 6, the upper surface of the end portion 33 ofthe member 18 will contact with the roller 27 and will thus support andprevent any down ward movement of the shaft 16.

Assuming the doors to be in closed position and it is desired to openthem, the op erator by the use of lever 34 rotates the operating shaft16 in the direction as indi. cated by the arrows in the left handportion of Fig. 3 and Fig. 5, which causes the serrated roller 23 toengage with the serrated shoe member 22 on the doors 14 and 15, thuscausing the shaft to move in a horizontal direction from its doorsupporting position, as shown in the right hand portion of Fig. 3 and indotted lines in Fig. 5. It will be noted that the movable member travelshorizontally with the shaft until the shaft drops within the notches 26formed in the vertical web portions 25 of the member 24, at which timethe movable member is subjected to a tilting movement, allowing suchmember to assume a position as shown in dot and dash lines in Fig. 5 ofthe drawings, and indi cated by the reference character A. To preventfurther movement of the movable men"- ber 18 around the roller 28, astop 35 is provided, such stop being preferably integral with thevertical web members 25.

When it is desired to close the discharge doors the operator rotates theshaft 16 in the direction as indicated by the arrow in the right handhalf of Fig. 3 of the drawings until the chains 20 winding on the drums19 have raised the doors to a position above the shaft at which time thecontinued rotation of the shaft and the wind-' ing of the chains thereoncause the shaft to move bodily a sufficient distance for the rollers 23to engage with the shoes 22 of the member 21 to effect the final closingmovement of the doors. As the shaft moves toward and under the doors themember 18 will be drawn by the shaft from its nonsupporting position asshown in dot and dash lines and. indicated by the reference character Ain Fig. 5 to its supporting position as shown in full lines in thisfigure.

To stiffen the side wall 8 above the bracket 24, triangular members 36are preferably provided which are secured to the stake l2 and to thesloping and horizontal portions 1.0 and 11 respectively of the sidewall.

It will be 'iuulcrstood that if desired the men'ibers 18 which have beendescribed as bcing secured to the transverse members of the underframemay be dispensed with and the movable member and bracket may besubstituted at intervals throughout the length of the operating shaftfor the support of such shaft.

In the drawings, the door 15 has been shown about twice the length ofthe doors 14, but it will be understood that if desired the door 15 maybe of a length great enough to extend between the bolsters, or ifdesired all the doors may be made of equal length, or in other words,all the doors may be of substantially the same length as the doors 14.

I do not wish to be limited to the exact construction and arrangement ofthe parts of the door operating mechanism as described in thespecifications, for it will be apparent to those skilled in the art towhich this invention appertains that many changes may be made withoutdeparting from the spirit and scope of the invention, as set forth inthe appended claims.
